Figure F21. Resistivity-at-the-bit image (dynamic scaling) of basaltic basement at the base of Hole 1173B. Image shows a near-vertical conductive contact (indicated by green arrows) just below the contact between volcaniclastics and basalt. The conductive feature is interpreted as a drilling-induced borehole breakout. This feature is cut by two high-angle fractures (73° and 68° dips; blue sinusoids). Fracture information is given as dip and dip azimuth.
